y G. A. cARLsoN LEVER sAsH EGULAToR Filed Oct. 27, 1924 2 Sheets-Sheetl 2 best; shown in Figs. 4, 6 and 10. As a result of this resilient coiled clutch arrangement the inherent tendency of the spring gripping the stationary bushing 20, is to hold the abutment member 34 and the pinion 83 station` ary, thereby preventing accidental movement of the sash $3 because of its weight or vibrations to which it may be subjected during the operation ot an automobile. The clutch braking device does notl however7 prevent rotation ol the arbor 23 when the sash 3 is to be manually adjusted. ll'hen the arbor Q3 is rotated in either direction the spring abutment member 34; is turned and one ot' its abutinents will cause the spring to uncoil or expand suficiently relative to the bushinfY :'20 to permit oi the follower Q7. the spring abutment member 34 and the pinion to rotate in synchronisn'l and thereby actuate the sector gear 10 carrying the lever 11. llVhen the arbor 2l-3 is released by the operator the retractile torce of the spring 3T causes it to `grip the bushing i2() again and by virtue of the ends of the spring engaging the abutments and 36 the member 34. the follower 2T and the pinions 33 will be stationary preventing actuation of the sector gear 10 by the weight, ot the sash 3.

I attach considerable importance to the tact that the plate 8 and the mechanism supported thereby is a bench assembled structure that can be easily and quickly installed in a sash Well, and furthermore that the majority of the elements are stampings that may be easily and quickly assembled. It is for this reason that the lever l1 is made separate from the sector gear ltl and al'tcrwards secured thereto along one ol the edges ot the sector gear so that there will be a lercrage action when adjusting the sash 2i.

Obviously such changes may be in the construction olf my device ae are permissible by the appended claim.

lVhat l claim is:-

ln a clutch-` a cnp-shapcd cafing. a hnshing;` non-rotatably secured against tlnI outer all nl laaid casing and c itcndingy therein, an arbor in -said bushing, a spindle extending into Said arbor, and means in said casingr frictionally engaging .said bushing adapted for holding said arbor and spindle against accidental rotation, said meansl including an abutment member. rotatable with said arbor and having abutments extendingr parallel to said bushing, a follower rotatable with said spindle and having a lng orerlying eaid abutment member and extending parallel to the abutments ot' said member. and a .spring frictionally encircling said bushing and haring its ends extending between the abutmentsy of said abutment member and the lug of said follower and adapted to he difitended to permit rotation of said arbor and spindle.

In testimony whereof l aflix mv signature.
